I took a trip on the new LUAS extension today (21st October 2010)
The line has been extended to the Brides Glen. There are two 'ghost' stops along the route.
These are future planned stops.
This video clip is in High Definition and shows the approach to the stop called Leopardstown Valley.
Take note as the camera pans to the ticket machines. There's a lady dressed in black who runs away out of view of the camera! You will see here at exactly 0:39
(I only noticed this when i played back the clip!)
